Rapidly increasing growth and demand in CNS/ATM, the advanced scheme for air traffic management, ADS-B system which is based on digital communication is being implemented in the field of surveillance. ADS-B concept appears to be an economically viable solution to obtain accurate aircraft position information. ADS-B system has better performance than the traditional radar and ADS-B system replace the radar in the near future. However, as the position information of the ADS-B is obtained from the GPS, the accuracy of the ADS-B lies on GPS. Therefore, the ADS-B information includes GPS errors. In this paper, we applied the unscented kalman filter to the ADS-B information to improve the accuracy of the ADS-B information. Comparisons with the original ADS-B information and the ADS-B information with the unscented kalman filter show that the ADS-B information with the unscented kalman filter provides the better.
